They previously repurposed the zombie sub-genre, with a rather hilarious skit titled "Suburban Zombies," which considered zombies with a racial bias. And now Key and Peele, in a teaser for the upcoming 4th season of their Comedy Central show (which premieres next week Wednesday, September 24), are doing the same with the alien invasion sub-genre of movies, in a skit titled "Alien Imposters," which imagines an alien invasion, as our 2 heroes roam the earth, carrying guns to protect themselves against "imposters" they encounter along the way. And the only way to determine which humans are actually human, and which are aliens in disguise, is to ask them coded questions that indicate their racial biases.
